Separation Characteristics
The membrane is specifically designed to preferentially reject divalent ions including:
Calcium (Ca²⁺),Magnesium (Mg²⁺),Sulfate (SO₄²⁻),Heavy metal ions
Natural organic matter,Color compounds
Medium molecular weight organic contaminants
At the same time, a portion of monovalent ions can pass through the membrane, making it suitable for applications requiring partial desalination rather than complete salt removal.
